ESI 307M Fuse Buddy Mini Current Loop

I work as a professional auto mechanic. I am an ASE Master Tech with advanced certification. I purchased this Fuse Buddy to use with my Snap-on Low Amp Clamp. With this Fuse Buddy I am able to plug it into the fuse and then clamp my low amp clamp around the loop and diagnose a circuit. When I purchased this I was going to diagnose a problem with a fuel pump. With the Fuse Buddy I didnt have to go under the car I could easily do my diagnoses with my amp clamp and the fuse buddy. The best part of it was when the problem happened I could see that I was still getting normal amperage to the fuel pump so I knew then that the problem was not with the fuel pump. These Fuse Buddys are a great find for anyone working in the field and wants to save a little time. The best part is that you can use them on any electrical circuit that requires a fuse. This comes in real handy when the component you want to test is hard to get to such as a fuel pump. Most automotive electrical devices are in series with the fuse so if you check the wiring diagram and this is the case then the amperage will be the same threw out the circuit. Like I said these Fuse Buddys are GREAT!!!!!!!!!!

These work really well but dont fit just everywhere. Several times Ive wished that these had a skinnier body that would allow for more clearance and better fitment as well as more applications. When it does fit it works well.

It work just as advertized. Perfect for my work.

The fuse but he is very nice I would recommend, if they have it where it fits multiple sizes to get the multiple sizes at that time.

Nice item very useful

This is a great product to assist in the measurement of current draw in automobiles, but requires a non-contact DC digital clamp meter. The quality, design and construction of this product rate a 5 star rating.

Side fuse holder not very straight seems to be that way on all of them i have several. Still works with wiggle it and hard push or pull to get it out . Just poor Chinese quality control. Still good product

Cheaply made in China item. Have screwdriver and pliers handy to remove fuse as once installed no way to grab top of fuse by hand. Cheap metal contacts that dont line up and cheap loop wire. Not for professional use.

Perfect product enough said
